    It seems that in the general desire to acknowledge and recognize the contributions of science to our present society, there is a tendency to glamorize the basic sciences at the expense of their engineering counterparts. It is almost as if a descending hierarchy has been established between theory at one end and practice at the other. Perhaps this is not the case, but articles on the danger of negl...

    A member of Philips Research Laboratory, Eindhoven, Holland, has used a new method to calculate the radiation impedance of a linear antenna in a waveguide of rectangular cross-section, viz., Schwingers' variational principle. This new application, even when based on only a two-term Fourier expansion of the current distribution, gives better results than a sinusoidal current distribution. View full abstract»

    Cited by:  Papers (8)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (471 KB)

    The theory and operating characteristics of a new type of high performance reflective switch is given. It utilizes the cut-off phenomenon in transversely-magnetized ferrites. The insertion loss of the device is 0.4 db and over 60 db within the 8.8 to 9.5 kmc band when the ferrite is demagnetized and magnetized respectively. The reflection coefficient of the switch in the "off" state is more than 9... View full abstract»

    The paper describes some results of a theoretical and experimental investigation of the propagation behavior of circular cylindrical wave guides containing longitudinally magnetized ferrite rods. As long as no concentration of the RF-magnetic field in the ferrite occurs, theoretical expressions for the propagation constants can be given by applying first-order perturbation method.

    Cited by:  Papers (7)

    In conventional microwave impedance measuring the measured ratio of maximum to minimum detector signal level is ideally equal to the voltage standing-wave ratio (VSWR) of the termination. In this paper, it is shown how radically types of response are obtainable in which the observed ratio may approximately equal the square of the VSWR or may be magnified any desired amount.

    A rigorous analysis of the microwave retlectometer is presented for what is believed to be the first time. By means of this analysis, the correct adjustment of auxiliary tuners is described, and the errors resulting from incorrect adjustments are treated in a quantitative manner.

    A microwave receiver using a single-circuit backward-wave amplifier as a combination radio-frequency ampliier and homodyne local oscillator is described. The amplitler tube is operated at a value of beam current just above that required to maintain oscillation. It is shown that in this way, the high gain and narrow bandwidth of the single-circuit backward-wave amplifier may be utilized in an elect... View full abstract»

    In this paper, an operator T0 is introduced for the analysis of the periodically distributed parametric amplifier. The operator is the product of a diagonal matrix expressing the pumping phase relation and the T matrix of the basic section of the amplifier. The eigenvectors of T0 are called the "modes" of the amplifier. The orthogonality properties of the modes are proved in a similar way as for t... View full abstract»

    Relations are investigated between the transmission characteristics of a helix waveguide and its surface impedance in regions where any simple approximate formulas are not available because of the magnitude of the surface impedance. The numericaf calculations show that, for any given value of the surface impedance and the angular mode index, there exist an infinite number of different modes which ... View full abstract»

    An L-band diplexing filter has been constructed with an estimated power-carrying capacity of S megw at atmospheric pressure (for a power safety factor of nearly four to one) and an insertion loss of less than 0.1 db. The filter consists of two hybrid junctions and two high pass waveguide sections, which are arranged as in a balanced duplexer, with the "TR-tubes" replaced by the high-pass sections....

    In the application of microwave refractometers, the sampling cavity consists of a right circular cylinder whose parallel faces are partially opened to permit air flow. The ambient air is aspirated through the cavity, and the instrument measures a weighted average of the index of the air contained at any time within the cavity. View full abstract»

    This paper summarizes a Ph.D. dissertation on the design and analysis of open-ended microwave cavities. The study was motivated by the need for a cavity with a high measure of quality, Q, through which an unobstructed flow of gases or particulate matter could be obtained. Used in collection with the Crain refractometer, instantaneous measurements of the refractive index of the material in the cavi... View full abstract»

    The transverse electric field distribution in dielectric and ferrite loaded waveguides has been measured by several investigators. Knowledge of the actual field distribution within the waveguide is needed in the design of field displacement isolators, phase-shifters, and similar microwave devices. In making such measurements, care must be taken to choose lengths of samples of ferrites or dielectri... View full abstract»

    A problem frequently arising in microwave electronics is the feeding of pulsed power from a self-excited source into a high-Q resonant load. A typical example is the one of feeding power from a pulsed magnetron into a high-Q microwave cavity such as that used in a linear accelerator. In the past, it has been customary to use a stabilizing load in a series tee system which results in approximately ... View full abstract»
